Upon contraction of the boiler the arch will rock back into itsnormal position.v The' end expansion of the boiler due to heat willoperate to rock the rear arch 27 in zi similar manner upon the plate 29,and upon contraction of thc boiler the arch will rock back into itsnormal position as shown in Fig. 2.

Variations 'in the construction nuiy be Inode to accomplish the saineresult but desire to claim all such variations and n1odificotions asfall within the Spirit of my invention.

What I claim iS: i l. A boiler` setting comprising i'nclosing wolle, eplate on the upper edge of said walls having a plane face and Shoulderand. en inclined face formed thereon, an arch section consl'ructed onits lower edge toengfige said plane face end'soid shoulder, and providedwiban inclined face disposed opposite to Said walls formed with oshoulder and un inclined face thereon, a boiler, 'laggin posi.- tionedlthereon, arch Sections arrange said boiler and being constructed ontheir lower edges to rest upon said plete and to rock thereon againstSuid ehouldertowerd said inclined face, and lheir'npper edges hc ingprovided With a lop joint, whereby said arch Sections may rock under theiniluence of the expansion of the boiler.

In testimony whereof l nliX my signature in the presence of twowitnesses. v
